Hi there,I would like to execute some code in an interrupt handler when the pulse value for TIM16 is reached. But for some reason, none of the interrupts provided by HAL seem to trigger for this event.I have setup the timer using the configuration tool with the following:(TIM 16 running off an 8MHz clock)CH 1 - PWM Generation CH1Prescaler - 799ARR - 9999Mode - PWM mode 1Pulse - 2499I assigned pin PB8 to produce the PWM signal.To start the timer I have made the call:/* USER CODE BEGIN 2 */ HAL_TIM_PWM_Start_IT(&htim16, TIM_CHANNEL_1); /* USER CODE END 2 */I am using a scope to check that indeed there is a PWM signal on PB8 with a duty cycle of 25% and a period of 1s. As expected.I have placed LED toggling code inside the following interrupts:HAL_TIM_PeriodElapsedCallbackHAL_TIM_PeriodElapsedHalfCpltCallbackHAL_TIM_OC_DelayElapsedCallbackHAL_TIM_PWM_PulseFinishedCallbackHAL_TIM_PWM_PulseFinishedHalfCpltCallbackHAL_TIM_TriggerCallbackHAL_TIM_TriggerHalfCpltCallbackHAL_TIM_ErrorCallbac

Hi Team,I am using the stm32h745ziq as my development board to develop the FDCAN. To implement this I am not able to find any example for this FDCAN to this particular board.Can you please send me any FDCAN example program to this NUCLEO-STM32H745.Best Regardssm.

I am on a robotic forum where we have been studying using this VL53L5CX for robotic vision, mapping and SLAM for the last two months. We are on page 12 of this thread: "<link provided if requested and I'm permitted>"The problem we have run into concerns the distance readings we're getting out of it. The problem is explained in detail in the second half of this post "<link provided if requested and I'm permitted>" with pictures and previous posts to that thread give detailed output from the sensor.Since I am new to this forum and can't provide the links, I'll summarize the problem here:We have the sensor square-on to a wall 1000 mm away.The wall is house-painted whiteThe ambient lighting is very low (barely readable)Since the FoV angle from corner to corner is ~64 degrees, the corner distances should follow standard Trigonometry theory and be further away than the central pixels.Theory says, if the center is 1000 mm away, the distance to the center of all four corner pixels

I have a setting which can be manually or automatically adjusted/changed. A toggle button selection choses manual or automatic adjustment. Manual adjustment is done using a slider widget. When the toggle button is selected to automatic position, slider position will be adjusted programmatically based on auto adjusted value. In this case, I want slider to be disabled for manual adjustment i.e. slider head shouldn't move if attempted to slide manually. How can I achieve that?I tried by making a grey image appear on top of slider when automatic selection is made hoping that slider will not move because this grey image is on top layer now compared to slider. Moreover, the grey image gives slider disable appearance as well. But it did not work. Please let me know.

Hello,I want to apologize in advance for how long this post is. I wanted to provide as much information as I could so I can help you (the reader) get a better picture of what might be going on. Sorry.I am currently working on a project that uses a st25r3914 nfc chip to detect and interface with an NFCa tag. Also, I am using the pre-made RFAL for ST25R3911B library so I can get the chip up and running quickly. Unfortunately, this process has not been going so well. I am running into issues interfacing with a tag.Background InfoNFC Chip - ST25R3914NFC Lib - RFAL for ST25R3911BMCU - NXP S32K144OS: NXP freeRTOSI have successfully merged the pre-made library with the rest of my code and have populated the platform.h header file with all that is necessary. To test if the library is setup correctly, I am using the exampleRfalNfca.c example program that came with the documentation. I have verified that the system is initializing the RFAL lib correctly given that the return of the function rfal

stm32cube mx just generate flash.ld linker script. So I create my own ram.ld linker script, also i modify system_stm32g0xx.c to point the entry point to sram /* Note: Following vector table addresses must be defined in line with linker configuration. */ /*!< Uncomment the following line if you need to relocate the vector table anywhere in Flash or Sram, else the vector table is kept at the automatic remap of boot address selected */ #define USER_VECT_TAB_ADDRESS   #if defined(USER_VECT_TAB_ADDRESS) /*!< Uncomment the following line if you need to relocate your vector Table in Sram else user remap will be done in Flash. */ #define VECT_TAB_SRAM #if defined(VECT_TAB_SRAM) #define VECT_TAB_BASE_ADDRESS SRAM_BASE /*!< Vector Table base address field.

I want create one app that with NFC read the memory of ST25DV64K-I.i try the official app ST25 and read the memory... but using the st25sdk-1.10.0 libraries.i use android studio.i can read the Tag name and UID, but i can't find how to read the memory

I am Using ST25R3914-AQWT NFC chip as a Slave Device and Renesas RL78 as Master device for SPI communication. When I tried to interface both controller MISO signal is shifted to 1.2V

For the package LQFP48 the pinout is the same. Also Pin names are the same. So is it possible ?

Hello,I am following this guide: https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_PackageI have reached step 6, but when I run bitbake st-image-weston I'm getting this error:DEBUG: Executing python function populate_packages ERROR: QA Issue: icu: Files/directories were installed but not shipped in any package: /usr/lib/lib Please set FILES such that these items are packaged. Alternatively if they are unneeded, avoid installing them or delete them within do_install. icu: 1 installed and not shipped files. [installed-vs-shipped]Before that, I used this command: DISTRO=openstlinux-weston MACHINE=stm32mp13-disco source layers/meta-st/scripts/envsetup.shDo you know what can I do to fix this error?

Hello,I have a problem updating the Wireless Stack on STM32WB55CGU6 on a custom board. The board is basically a cloned version of the P-NUCLEO-WB55-USBDONGLE. The device is connected via SWD on St-Link/V2.FUS Version is already on v1.2 from Factory, but there is no STACK installed.Whenever I try to install a new BLE Stack, there are two possibilities:Either a ‘Error: FUS_STATE_ERR_UNKNOWN’ or everything appears to go fine, showing ‘success’. But either way, afterwards it appears there is no STACK installed.This is exactly the same for different Wireless Bundles and different Version Numbers.I tried 1.13.1, 1.13.3, 1.14.0 and 1.14.1 with stm32wb5x_BLE_Stack_full_fw.bin, stm32wb5x_BLE_Stack_light_fw.bin and stm32wb5x_BLE_Stack_full_extended_fw.binThe strange part is, that it already worked on one board, doing exactly the same thing!But it doesn’t matter how many times I try, it doesn’t work on the other boards.It is exactly the same thing when trying to update the STACK with the CLI Prog

Hi,When searching "L78M12", there are two results in ST web site. One says that "L78M12AB" is obsolete. The other one says "L78M" is active. For both of them, there are links to datasheets. One datasheet is obsolete and the other one is active. I look for "L78M12ABDT-TR". This part is referenced in both datasheets and I am confused about the state of this part. Any one who can help?Thank you so much,

when i configure spc58nn project ,there is pineditor and clock tree ,the configurtion gui. and i cant find any other peripheral configuration gui,any one know this?

I am a bit frustrated with the USART2, which is connected to the UART9 TX9-RX2 and TX2-RX9. So with sending from TX9 to RX2 everything is fine but the other way around there is a first byte = 254d inside the receive buffer. huart2 and huart9 are initialized totally equal asynchronous with the default CubeIDE configuration. huart9.Instance = UART9; huart9.Init.BaudRate = 115200; huart9.Init.WordLength = UART_WORDLENGTH_8B; huart9.Init.StopBits = UART_STOPBITS_1; huart9.Init.Parity = UART_PARITY_NONE; huart9.Init.Mode = UART_MODE_TX_RX; huart9.Init.HwFlowCtl = UART_HWCONTROL_NONE; huart9.Init.OverSampling = UART_OVERSAMPLING_16; huart9.Init.OneBitSampling = UART_ONE_BIT_SAMPLE_DISABLE; huart9.Init.ClockPrescaler = UART_PRESCALER_DIV1; huart9.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_TXINVERT_INIT; after Init I do this in the main() routine:uint8_t cnt = 0u; uint8_t strU9Sent[6u]; uint8_t strU2Received[6u];   sprintf((char *)strU9Sent, "hello", cnt); HAL_UART_Recei

Hi,I would like to ask for help about STM product with part number F271-BAR5-T-TX. STM10F271 has details about F271-BAG5-T-TR parts but I cannot find a reference for the BAR5 code and its meaning. I would greatly appreciate any help to clarify the issue. Thanks.Regards,Louie

I have been using the ST25RU3993HPEV board for the Tag detection. Earlier the board is performing well and it was detecting tag. But suddenly reader is not detecting tag.Is there any chance for power amplifier regulator has gone bad? If the tag is kept on the surface of the antenna, it will be detected at some point.

Hi everybody, I'm trying to delete a single sector of my STM32L4P5G Discovery Board MX25UM51245G OctoSPI Flash memory but I always end up in a timeout. Reading memory by function BSP_OSPI_NOR_Read() is working as expected. I'm using the bord support code of the STM32L45R Evaluation Board. The timeout occurs within OSPI_NOR_WriteEnable() function call caused by the command HAL_OSPI_Receive(). My board is running at 120MHz. I will add the files as attachment and post the relevant functions here. Be aware I adapted the OSPI_NOR_MspInit() to match the other hardware. I used the app note AN5050 to bring the flash to memory mapped mode what is working as expected. But for flash manipulation I require the indirect mode. Does anyone have an idea why I end up in a timeout?uint8_t BSP_OSPI_NOR_Erase_Sector(uint32_t Sector) { OSPI_RegularCmdTypeDef sCommand;   if (Sector >= (uint32_t)(MX25LM51245G_FLASH_SIZE/MX25LM51245G_SECTOR_SIZE)) { return OSPI_NOR_ERROR; }   /* Initialize

Hello,I think it is easy to connect nucleo64-boards (e.g. NUCLEO-F303RE) and X-NUCLEO-IHM08M1. Is it possible to connect NUCLEO-F746ZG and X-NUCLEO-IHM08M1 in the same way?I am concerned about the size of the nucleo144-boards and whether they will interfere with the X-NUCLEO-IHM08M1 and whether the pins will fit.Thanks in advance
